Filed Dec. 27, 1965, Ser. No. 517,197 2 (Zlairns. (Cl. 49-383) Thisinvention relates to a door with sealing means.

One object of our invention is to provide improved sealing means betweenan inner side extremity of a door and the door jamb to thereby close orseal the space between the two.

Another object is to provide effective sealing means that is not carriedby the door yet keeps the space sealed between the door jamb and door.

Still another object is to provide novel sealing means carried by thedoor whereby the said space is kept sealed normally and as the door isopened and closed.

A further object is to provide such sealing means in the form of a loopthat contacts the door jamb, thus providing a flexible sealer of doublethickness having a sturdy appearance.

A still further object is to provide such sealing means that is simpleto install, is durable, and relatively inexpensive to manufacture.

The foregoing and other objects which will appear as the nature of theinvention is better understood, may be accomplished by a construction,combination and arrangement of parts such as is disclosed by thedrawing. The nature of the invention is such as to render it susceptibleto various changes and modifications, and therefore, we are not to belimited to the construction disclosed by the drawing nor to theparticular parts described in the specification; but are entitled to allsuch changes therefrom as fall within the scope of our claims.

In the drawing:

FIG. 1 is a front elevational view of a door embodying our invention.

FIG. 2 is an enlarged, sectional view taken on the line 22 of FIG. 1.

FIG. 3 is a greatly enlarged, fragmentary, front elevational view of theupper left corner of the door shown in FIG. 1.

FIG. 4 is an enlarged, sectional view taken on the line 44 of FIG. 1.

FIG. 5 is a front elevational view showing the mounting means connectingthe door to the door jamb at the upper left corner.

As illustrated, my door has a main body having at an inner side a woodblock or stile 12. As shown, said body includes a pair of rubber covers14 and 16 at the rear face and a pair of rubber covers 14a and 16a atthe front face. Between said pairs of covers is a filler of rubberizedhair 18 or any suitable material.

Said door has a support for said body 10 shown as a rotatable post 20which provides part of the mounting means by which said body 10 movesbetween closed and open position. This post 20 is set in a bearing 21attached by a bolt 21a to a door jamb 30, later described. Said post 20is connected to said body 10 by two metal attaching portions 22 and 22athat are fastened to said stile 12 by screws 24 which also pass throughsaid covers.

3,384,995 Patented May 28, 1968 Well known cam mounting means 25 extendsabove the top of said two pairs of covers and includes a bearing 26 heldby bolts 28 to a door jamb or frame 30 and that has a cam member 32.

A roller holder 33 supports a roller 34 that runs on the surface of saidcam member 32, being rotatably held by a pin 38 to a support or yoke 36.A pin 40 fixedly holds said cam holder 33 to said post 20, thusrotatably moving the post and holder together. This causes said camroller 34- to travel on the surface of said cam portion 32 as the dooropens and closes and also respectively raises and lowers the latter.

Between said mounting means 25 and said door jamb 30 there is a space 42which will permit air to pass through. To close this space at all times,we provide sealing member 44 overlapping a portion of said body 10 andshown as a flexible flap normally in contact with said body 10. Thismember has an angular attaching portion 46 that extends into a U-shapedholder 48 and is there held by screws 50 that extend through said holder48, said attaching portion 46 and into said door jamb 30. This sealingmember 44 may be made of neoprene or other durable and flexiblematerial.

Below said mounting means 25 and sealing member 44 is another closure orair sealing member 54, that may be made of flexible material such asHypalon. It extends mostly around said post 20, and through a spacebetween said attaching portions 22 and 22a. Beyond the latter it is soformed as to provide a closure loop 56 that contacts said jamb 30 thusproviding an air seal extending downwardly from said air sealing member44. Thus the space between said jamb 30 and said door opposite said loop56 is always sealed or closed, whether the door is moving or still.

Said sealing member 54 is fastened by a pin member shown as a rivet 58extending through attaching portions 22 and 22a, sealing member 54 andpost 20, being headed over as at 60.

What we claim is:

1. A door in combination with a door jamb, said door embodying mountingmeans movably mounting said door to said jamb, said jamb being spacedfrom the inner side edge of said door, and a flexible sealing memberattached to said jamb and normally in contact with a portion of saiddoor, said sealing member extending only partly the height of said door,and another sealing member attached to said door and extending in theform of a loop to and into contact with said jamb and extending from apoint adjacent said first sealing member in a direction away from thelatter.

2. A door in combination with a door jamb as set forth in claim 1, saidmounting means embodying a post extending vertically, said other sealingmember extending partly around said post, and means holding said othersealing member to said post.
